If $A$ and $B$ are arbitrary constants,then the differential equation having $y=Ae^{x}+B \sin 2 x$ as its general solution is

• A
  $\begin{aligned} &(\cos 2 x-\sin 2 x) \frac{d^2 y}{d x^2}+(4 \sin 2 x) \frac{d y}{d x}-4(\sin 2 x+\cos 2 x) y=0\end{aligned}$
• B
  $\begin{aligned} &(\cos 2 x+\sin 2 x) \frac{d^2 y}{d x^2}+(4 \sin 2 x) \frac{d y}{d x}-4(\sin 2 x-\cos 2 x) y=0\end{aligned}$
• C
  $\begin{aligned}(\cos 2 x-\sin 2 x) \frac{d^2 y}{d x^2}+(4 \sin 2 x) \frac{d y}{d x}+4(\sin 2 x+\cos 2 x) y=0\end{aligned}$
• D
  $\begin{array}{r}(\sin 2 x-\cos 2 x) \frac{d^2 y}{d x^2}-(4 \sin 2 x) \frac{d y}{d x}-4(\sin 2 x+\cos 2 x) y=0\end{array}$
